Range-for-statement in Modern C++

Since C++11 there are elegant way to access each element of a containers (or, more generally, sequences) – so called range-for-statement. The syntaxes are follow: template<class Container> void foo(Container& container) { for (auto element : container); // (1) for (const auto element : container); // (2) for (auto& element : container); // (3) for…

Reverse Iterators in C++

By using bidirectional iterator or random access iterator (see Iterator Categories in C++) it’s possible to traverse the sequence in backward direction by using operator -- or by using the special adapter template class std::reverse_iterator. But why to bother with reverse iterators if the operator -- is available for iterators with bidirectional traversing capabilities? The answer is…
